One principle important to understanding this phenomenon is used by radio engineers to find the ratio between metal and slot impedances. Electrons passing through a nickel crystal undergo this effect, as discovered by Davisson and Germer. Babinet showed the equivalence of two versions of this phenomenon, and one version of it is described by a formula with a constant of 1.22. Fresnel and Fraunhofer name the near and far-field versions of this phenomenon, which is also described in terms of wavefronts by Huygens principle. It produces an Airy disk when occurring in a small hole. This behavior also occurs in a double-sl

For 10 points, name this phenomenon in which light bends as it passes through an opening or around an object.
